Internet Printing Protocol/1.1: Encoding and Transport
Status of this Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.

Abstract
This document is one of a set of documents, which together describe
all aspects of a new Internet Printing Protocol (IPP). IPP is an
application level protocol that can be used for distributed printing
using Internet tools and technologies. This document defines the
rules for encoding IPP operations and IPP attributes into a new
Internet mime media type called "application/ipp". This document
also defines the rules for transporting over Hypertext Transfer
Protocol (HTTP) a message body whose Content-Type is
"application/ipp". This document defines a new scheme named 'ipp' for
identifying IPP printers and jobs.

RFC 2910 IPP/1.1: Encoding and Transport September 2000
The full set of IPP documents includes:
Design Goals for an Internet Printing Protocol [RFC2567]
Rationale for the Structure and Model and Protocol for the Internet
Printing Protocol [RFC2568]
Internet Printing Protocol/1.1: Model and Semantics [RFC2911]
Internet Printing Protocol/1.1: Encoding and Transport (this
document)
Internet Printing Protocol/1.1: Implementer's Guide [ipp-iig]
Mapping between LPD and IPP Protocols [RFC2569]
The document, "Design Goals for an Internet Printing Protocol", takes
a broad look at distributed printing functionality, and it enumerates
real-life scenarios that help to clarify the features that need to be
included in a printing protocol for the Internet. It identifies
requirements for three types of users: end users, operators, and
administrators. It calls out a subset of end user requirements that
are satisfied in IPP/1.1. A few OPTIONAL operator operations have
been added to IPP/1.1.
The document, "Rationale for the Structure and Model and Protocol for
the Internet Printing Protocol", describes IPP from a high level
view, defines a roadmap for the various documents that form the suite
of IPP specification documents, and gives background and rationale
for the IETF working group's major decisions.
The document, "Internet Printing Protocol/1.1: Model and Semantics",
describes a simplified model with abstract objects, their attributes,
and their operations that are independent of encoding and transport.
It introduces a Printer and a Job object. The Job object optionally
supports multiple documents per Job. It also addresses security,
internationalization, and directory issues.
The document "Internet Printing Protocol/1.1: Implementer's Guide",
gives advice to implementers of IPP clients and IPP objects.
The document "Mapping between LPD and IPP Protocols", gives some
advice to implementers of gateways between IPP and LPD (Line Printer
Daemon) implementations.
